PSLE Learner’s Guide · Vol 0352 · Multiple-choice recovery, stem audit and controlled reopening
Find the exact decision this guide helps you make
This guide helps a Primary 6 learner recover when every multiple-choice option appears wrong by auditing the question stem, answer type, units, reference whole, copied data and rejection reasons before restarting the full solution. The short rule is when no option fits, audit the stem and rejection reasons before rebuilding the method. You will learn the mechanism, see worked examples, repair common misconceptions, practise in stages and use a compact examination routine.

For complete teaching, worked practice and topic progression beyond this performance decision, continue through the eduKate Learning Hubs. This volume keeps a narrower job: it helps the learner recognise, execute and check one examination decision without competing with the wider topic owner.

A careful note about the current examination year
This article is written for the 2026 PSLE preparation context. SEAB’s official 2026 formats page lists English Language as subject 0001, revised Mathematics as 0008 and revised Science as 0009. Format details can change, so confirm any paper-specific timing, component or administrative instruction with the current official SEAB 2026 source and your school. The reasoning routine taught here is deliberately broader: it strengthens how you read evidence, make a decision and check an answer.
Why this mistake happens
When no option survives, the examination has usually exposed a mismatch between the learner’s interpretation and the question. The learner may have missed not or except, answered for a part instead of the whole, converted a unit in one line but not the next, copied a number incorrectly, or eliminated the correct option with a faulty reason. Panic encourages a complete restart, which can reproduce the same misread. A short stem-first recovery protocol reopens the decision in a controlled order and preserves any work that remains valid.
The mind likes a fast label. A familiar word, operation, result or rule triggers an answer before the conditions have been checked. That shortcut sometimes works in easy practice, so it becomes a habit. In a demanding question, however, a nearby distractor preserves the surface pattern while changing one important condition. The learner then performs a correct-looking move on the wrong object. The repair is to slow only the decision point: identify what is being linked or measured, preserve its labels, test the conditions, and then continue at normal speed.
Think of the method as a chain with four locks. Object: what exact idea or quantity is under discussion? Relationship: how are the relevant parts connected? Condition: what must be true for the move to be valid? Claim: what is the strongest conclusion the evidence actually supports? A weak answer often skips from object to claim. A strong answer makes the two middle locks visible.
The one-line operating rule
When no option fits, audit the stem and rejection reasons before rebuilding the method. Say it before the first practice set. During timed work, shorten it to four cue words you can recall without stopping.
The step-by-step method
Step 1: Stop eliminating and mark the question as a recovery case instead of forcing the nearest option
Stop eliminating and mark the question as a recovery case instead of forcing the nearest option. Do this on the page, not only in your head. A brief arrow, label, unit, underline or condition note makes the decision inspectable. If you later find an error, you can repair the exact step instead of restarting the entire answer.
At this stage, do not decorate the answer with extra facts. Ask one diagnostic question: “What evidence would make this step wrong?” If you can name a possible failure, check it now. If the failure is absent, continue. This negative check prevents confidence from replacing proof.
Step 2: Re-read the stem alone and circle command words, negatives, qualifiers and the exact quantity or idea requested
Re-read the stem alone and circle command words, negatives, qualifiers and the exact quantity or idea requested. Do this on the page, not only in your head. A brief arrow, label, unit, underline or condition note makes the decision inspectable. If you later find an error, you can repair the exact step instead of restarting the entire answer.
At this stage, do not decorate the answer with extra facts. Ask one diagnostic question: “What evidence would make this step wrong?” If you can name a possible failure, check it now. If the failure is absent, continue. This negative check prevents confidence from replacing proof.
Step 3: Predict the required answer type, unit, sign, scale, reference whole or evidence strength before looking back at the options
Predict the required answer type, unit, sign, scale, reference whole or evidence strength before looking back at the options. Do this on the page, not only in your head. A brief arrow, label, unit, underline or condition note makes the decision inspectable. If you later find an error, you can repair the exact step instead of restarting the entire answer.
At this stage, do not decorate the answer with extra facts. Ask one diagnostic question: “What evidence would make this step wrong?” If you can name a possible failure, check it now. If the failure is absent, continue. This negative check prevents confidence from replacing proof.
Step 4: Check copied data, conversions and labels at the earliest point where the work could have changed meaning
Check copied data, conversions and labels at the earliest point where the work could have changed meaning. Do this on the page, not only in your head. A brief arrow, label, unit, underline or condition note makes the decision inspectable. If you later find an error, you can repair the exact step instead of restarting the entire answer.
At this stage, do not decorate the answer with extra facts. Ask one diagnostic question: “What evidence would make this step wrong?” If you can name a possible failure, check it now. If the failure is absent, continue. This negative check prevents confidence from replacing proof.
Step 5: Revisit each rejection reason and reopen any option whose reason fails under the corrected reading
Revisit each rejection reason and reopen any option whose reason fails under the corrected reading. Do this on the page, not only in your head. A brief arrow, label, unit, underline or condition note makes the decision inspectable. If you later find an error, you can repair the exact step instead of restarting the entire answer.
At this stage, do not decorate the answer with extra facts. Ask one diagnostic question: “What evidence would make this step wrong?” If you can name a possible failure, check it now. If the failure is absent, continue. This negative check prevents confidence from replacing proof.
Step 6: If one option now satisfies every condition, select it and perform a positive check; if uncertainty remains, flag the item and return within a time budget
If one option now satisfies every condition, select it and perform a positive check; if uncertainty remains, flag the item and return within a time budget. Do this on the page, not only in your head. A brief arrow, label, unit, underline or condition note makes the decision inspectable. If you later find an error, you can repair the exact step instead of restarting the entire answer.
At this stage, do not decorate the answer with extra facts. Ask one diagnostic question: “What evidence would make this step wrong?” If you can name a possible failure, check it now. If the failure is absent, continue. This negative check prevents confidence from replacing proof.
Misconceptions to diagnose and repair
Misconception 1
Tempting move: Choosing the numerically closest option even though it answers the wrong quantity. This feels efficient because it removes a decision. It is unsafe because the question may have changed the reference, unit, interval, definition or strength of claim.
Repair: return to the line, number, setup or statement that supplies the condition. Mark it with a short label. Then rebuild only the affected link. Keep all earlier work that remains valid. The purpose of checking is targeted correction, not anxious repetition.
Misconception 2
Tempting move: Restarting all calculations before checking a missed negative word. This feels efficient because it removes a decision. It is unsafe because the question may have changed the reference, unit, interval, definition or strength of claim.
Repair: return to the line, number, setup or statement that supplies the condition. Mark it with a short label. Then rebuild only the affected link. Keep all earlier work that remains valid. The purpose of checking is targeted correction, not anxious repetition.
Misconception 3
Tempting move: Keeping every option crossed out after discovering that one rejection reason was invalid. This feels efficient because it removes a decision. It is unsafe because the question may have changed the reference, unit, interval, definition or strength of claim.
Repair: return to the line, number, setup or statement that supplies the condition. Mark it with a short label. Then rebuild only the affected link. Keep all earlier work that remains valid. The purpose of checking is targeted correction, not anxious repetition.
Misconception 4
Tempting move: Changing the method repeatedly when the original method was correct but the unit conversion was not. This feels efficient because it removes a decision. It is unsafe because the question may have changed the reference, unit, interval, definition or strength of claim.
Repair: return to the line, number, setup or statement that supplies the condition. Mark it with a short label. Then rebuild only the affected link. Keep all earlier work that remains valid. The purpose of checking is targeted correction, not anxious repetition.
Misconception 5
Tempting move: Spending unlimited time on one item instead of leaving a controlled return marker. This feels efficient because it removes a decision. It is unsafe because the question may have changed the reference, unit, interval, definition or strength of claim.
Repair: return to the line, number, setup or statement that supplies the condition. Mark it with a short label. Then rebuild only the affected link. Keep all earlier work that remains valid. The purpose of checking is targeted correction, not anxious repetition.
Eight worked cases
Worked case 1: Negative English stem
Scenario. A question asks which statement is not supported, but the learner eliminates every unsupported statement in the usual direction.
The tempting error. Concluding that the question has no correct option. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. Reopen the stem and mark not. The target is the one unsupported statement, so the earlier elimination direction was reversed. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Restore the option that lacks passage support and positively verify the other statements. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Rewrite the stem without the negative and compare the decision. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 2: Wrong referent
Scenario. All four comprehension options seem wrong after “this change” is interpreted as the nearest noun.
The tempting error. Forcing the least awkward option. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. Substitute the larger earlier event or decision into the sentence. A demonstrative phrase can refer to an action or whole idea, not only the nearest noun. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Reopen options rejected solely because of the wrong referent. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Draw an arrow from the phrase to the complete earlier idea. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 3: Area versus perimeter
Scenario. A learner calculates 24 cm², but the options are 18 cm, 20 cm, 22 cm and 24 cm.
The tempting error. Removing the unit mentally and choosing 24. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. The option units signal that the question asks for length, likely perimeter, not area. Re-read the final demand before reworking. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Calculate the requested linear quantity and compare it with the linear-unit options. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Predict the answer type before the next calculation. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 4: Percentage whole
Scenario. No percentage option matches because the learner divided a part by the remaining part rather than by the stated whole.
The tempting error. Trying different rounding rules. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. Reopen the stem and label numerator and denominator in words. Percentage depends on the reference whole. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Use part÷required whole×100%, then reopen the matching option. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Check whether the percentage can exceed 100% under the actual wording. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 5: Science observation question
Scenario. Every option seems incomplete because the learner expects a causal explanation, but all options describe visible changes.
The tempting error. Rejecting all options as “not scientific enough.” The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. The stem asks what was observed. The required answer type is a measurable or visible result, not the mechanism. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Choose the option that accurately states the observation. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Write a separate explanation only if another question requests it. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 6: Unit conversion slip
Scenario. A mass calculation gives 0.75, while options are 75 g, 750 g, 7.5 kg and 75 kg.
The tempting error. Selecting 0.75’s nearest-looking digits. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. Audit the unit line. If the result was 0.75 kg, it equals 750 g. The numerical representation changes with the unit. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Select 750 g after confirming the requested unit. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Convert it back to 0.75 kg as a reverse check. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 7: Copied data
Scenario. A bar is read as 36 when the scale marks 2 units per small interval and the top lies at 34.
The tempting error. Repeating the same calculation with more written steps. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. The method may be sound; the input is wrong. Re-read the scale and copied value before restarting the operation. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Replace the input, keep valid later structure and recalculate. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Point to the source of every copied number. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Worked case 8: Still uncertain after audit
Scenario. Two options remain plausible after the stem, units and work are checked.
The tempting error. Cycling between them without new evidence. The response may contain relevant knowledge, yet it does not answer the precise decision because one label or condition has been lost.
Work the mechanism. Name the exact condition that separates the two survivors and search only for that evidence. If time expires, mark a return cue and move on. Write the decisive evidence beside the step where it is used. This makes the reasoning readable to another person and prevents a later sentence from quietly changing the meaning.
Answer form. Choose only when one option passes the separating condition; otherwise return later within the planned budget. Notice that the answer carries both the conclusion and the reason that licenses it. It is complete without becoming a list of everything you know.
Check. Re-read the command word, substitute the conclusion into the original situation and ask whether every noun, number and comparison still has the same referent or unit. If the answer is stronger than the evidence, narrow it.
Delayed transfer. Do not reopen options already rejected for decisive, unchanged reasons. Do this variation after a gap, not immediately, so retrieval rather than imitation drives the solution.
Practice progression: from recognition to transfer
Round 1: mark only
Use six short items. Do not answer them. Mark the object, reference, unit, interval, condition or rule that controls the decision. The goal is accurate noticing without the burden of full writing.
Record the result as one of four codes: N for noticing error, M for method error, I for interpretation error, and C for checking error. Practise the weakest code with a fresh item. Do not repeat an entire worksheet when only one decision needs repair.
Round 2: explain the choice
Solve four items and add one sentence beginning “This is valid because…”. If the sentence merely repeats the answer, the condition is still hidden.
Record the result as one of four codes: N for noticing error, M for method error, I for interpretation error, and C for checking error. Practise the weakest code with a fresh item. Do not repeat an entire worksheet when only one decision needs repair.
Round 3: repair a wrong answer
Take four plausible wrong answers. Identify the earliest faulty link, preserve the correct work and rewrite only what must change. This develops error diagnosis rather than answer copying.
Record the result as one of four codes: N for noticing error, M for method error, I for interpretation error, and C for checking error. Practise the weakest code with a fresh item. Do not repeat an entire worksheet when only one decision needs repair.
Round 4: mixed questions
Mix this job with two older skills. Remove headings that reveal the topic. Decide which routine applies before solving. Selection is part of performance.
Record the result as one of four codes: N for noticing error, M for method error, I for interpretation error, and C for checking error. Practise the weakest code with a fresh item. Do not repeat an entire worksheet when only one decision needs repair.
Round 5: timed set
Use a small timed set with a fixed check budget. Mark a cue at the decision point, finish the answer, then perform one positive check and one rejection check.
Record the result as one of four codes: N for noticing error, M for method error, I for interpretation error, and C for checking error. Practise the weakest code with a fresh item. Do not repeat an entire worksheet when only one decision needs repair.
Round 6: delayed transfer
Return after two or three days with different surface details. Before seeing notes, write the one-line rule from memory and solve. Compare the new error pattern with the earlier one.
Record the result as one of four codes: N for noticing error, M for method error, I for interpretation error, and C for checking error. Practise the weakest code with a fresh item. Do not repeat an entire worksheet when only one decision needs repair.
Graded independent practice with explained answers
Practice 1: Negative word
Try it. The stem asks “Which is least likely?” but you chose the strongest evidence. What first?
Open the answer and explanation after attempting the question
Answer. Circle least and reverse the target.
Why. The command word changes what counts as correct before any option is tested.
Check or transfer. Restate the target in positive language.
Practice 2: Answer type
Try it. Your result is in cm² but every option is in cm. What should you audit?
Open the answer and explanation after attempting the question
Answer. Whether the question asks for area or a linear measure.
Why. Unit dimension reveals a likely mismatch in the requested quantity.
Check or transfer. Do not drop the exponent merely to match an option.
Practice 3: Reference whole
Try it. A percentage does not match any option. What label should you write?
Open the answer and explanation after attempting the question
Answer. Part over which whole.
Why. The denominator may be the original total, remaining total or subgroup.
Check or transfer. Name numerator and denominator in words.
Practice 4: Science output
Try it. All options are observations but your answer is an explanation. What should you reopen?
Open the answer and explanation after attempting the question
Answer. The command and answer type.
Why. The question may ask what was seen or measured rather than why it happened.
Check or transfer. Choose evidence at the requested level.
Practice 5: Rejection reason
Try it. You rejected option C because of a calculation mismatch, then corrected the calculation and it matches C. What now?
Open the answer and explanation after attempting the question
Answer. Reopen C.
Why. The decisive rejection reason has changed, so the elimination is no longer valid.
Check or transfer. Retest C against every other unchanged condition.
Practice 6: Time control
Try it. After one stem audit, two options remain and time is running. What should you do?
Open the answer and explanation after attempting the question
Answer. Mark the separating condition and a return cue, then continue.
Why. A controlled return protects the rest of the paper while preserving the exact unresolved issue.
Check or transfer. Return within a planned review budget, not from vague worry.
A compact practice log
- Question source and date
- Decision cue you marked
- Your first answer in one line
- Earliest wrong link, if any
- Corrected rule in twelve words or fewer
- Date for delayed transfer
- Whether the new item was solved without notes
A useful log is small enough to maintain. It should help you predict the next mistake, not become a scrapbook of completed pages.
Checking that tests meaning, not neatness
A check should have a target. First run a positive test: identify the evidence, calculation or condition that supports your answer. Then run a rejection test: name the closest tempting alternative and the exact reason it fails. This pair is more powerful than rereading the same line while hoping to feel certain.
Use a reverse check where possible. Reconstruct the original amount, replace a connector with its expanded meaning, map a conclusion back to the data, or apply the repaired rule to the apparent exception. Reverse checking exposes lost labels and unsupported leaps because the answer has to return to its source.
Stop when the check has answered a real question. Repeatedly changing a sound answer because it feels unfamiliar is not checking. If the object, relationship, condition and claim all remain consistent, keep the answer and move on.
Examination control
When time is tight, use the cue ORCC: Object, Relationship, Condition, Claim. Write only the smallest useful mark—an arrow, a unit, a time interval, a boundary or a qualifying word. The mark should prevent the known error without slowing the rest of the paper.
- Read the command word and identify the decision.
- Mark the object or quantity that must keep its identity.
- State the relationship or operation in plain language.
- Check the condition that makes it valid.
- Give the claim at the strength supported by evidence.
- Use one positive and one rejection check, then stop.
If you become stuck, do not produce a longer answer immediately. Shorten the task: write what is known, what must be decided and what condition separates the two best options. A precise partial structure often unlocks the next step and also makes any partial credit more defensible.
A seven-day delayed-transfer plan
- Day 1: learn the one-line rule and complete two worked cases with notes.
- Day 2: solve four short items without notes; classify errors by N, M, I or C.
- Day 3: mix two new items with two older PSLE skills and hide the topic labels.
- Day 4: explain one case aloud to a parent, tutor or imaginary learner in under two minutes.
- Day 5: complete a timed mini-set and use the ORCC marks only at decision points.
- Day 6: rest this skill or practise a different subject so memory has to consolidate.
- Day 7: attempt one unfamiliar transfer item, then write the smallest rule revision needed.
Success on Day 7 matters more than fluency immediately after reading. Delayed transfer shows whether you can retrieve the method, recognise its job under new surface details and control it without a model beside you.
Guidance for parents and tutors
Ask for the decision, not a performance speech. Useful prompts are: “What exactly are you deciding?”, “Which word, unit or condition controls it?”, “What is the closest wrong option?” and “How can you check without starting again?” These questions keep ownership with the learner while making thinking visible.
When an error occurs, locate its earliest point. Praise accurate diagnosis even before the final answer is corrected. If the learner repeatedly loses the same label, introduce one stable notation: arrows for reference, units beside remainders, interval brackets for rates, or boxes around claim conditions. Avoid adding several new routines at once.
Build variation gradually. Begin with clean examples, then add one plausible distractor, then mix the skill with older content, and finally delay the next attempt. A learner who succeeds only when the worksheet title names the method has learned recognition, not transfer.
Keep emotional temperature low. A surprising exception or remainder is information, not proof that the learner is “bad at” a subject. The practical question is which link changed. Once that link is named, practise a small set that isolates it and then return to mixed questions.
The independent-reader test
Before you call the skill secure, explain one solution to a reader who cannot see your thoughts. Name the starting information, the decision, the condition that controls it and the reason the rejected alternative fails. If the explanation depends on “you know what I mean”, a label is still missing. Add that label to the answer, then remove any sentence that does not help the reader follow the chain.
Next, cover the worked example and rebuild the method from a fresh prompt. Do not copy the surface details. Recover the sequence of decisions. This separates genuine control from familiarity with one page. A learner who can transfer the decision routine to new names, numbers or apparatus has a more dependable examination skill than a learner who can reproduce only the model answer.
Finally, compress the method without losing its safety condition. Write one sentence of no more than fifteen words, then test that sentence against an awkward case. If the short rule gives the wrong result, restore the missing condition. Good compression keeps the mechanism available under time pressure while the awkward case prevents the cue from becoming a careless shortcut.
A timed diagnosis drill
Set aside twelve minutes and choose three unfamiliar questions that could trigger this error. Spend the first minute identifying the decision in each question without solving it. Mark the object, relationship, condition and permitted claim. This preview is not wasted time: it prevents you from entering a long method before you know what the method must preserve.
Solve the three questions in the next eight minutes. After each answer, write one tiny prediction about what a correct answer should preserve: a reference word, a whole-number boundary, a pathway, a unit, a direction or an observable result. Then compare the finished answer with that prediction. If they disagree, repair the earliest link and keep the later work only when its meaning remains valid.
Use the final three minutes to classify the errors. A noticing error means the controlling detail was never marked. A method error means the right information was present but the wrong operation or reasoning chain was used. An interpretation error means the result was calculated or observed correctly but described at the wrong level. A checking error means the answer contained a detectable contradiction that the final audit missed.
Repeat the drill a week later with different surface details and without looking at the old corrections. Improvement is not merely a higher score. Look for a shorter pause at the decision point, fewer unnecessary restarts, more stable labels and a clearer reason for rejecting the nearest wrong answer. Those are signs that the performance routine is becoming portable.
Frequently asked questions
Does no matching option mean the paper is wrong?
Usually audit your interpretation, labels and work first; do not assume an error without strong evidence.
What should I check before recalculating?
Command word, negative, answer type, unit, reference whole and copied data.
Should I erase every rejection mark?
No. Reopen only options whose rejection reason has changed or failed.
What if the method is correct but the unit is wrong?
Preserve the method, correct the conversion and update the dependent result.
How long should recovery take?
Use a short predetermined budget, then leave a precise return marker if needed.
Can option units help?
Yes. They can expose whether the question asks for length, area, volume, mass, time or another quantity.
What is the positive check after recovery?
State the evidence or calculation that makes the selected option satisfy every stem condition.
What should I practise next?
Use mixed English, Mathematics and Science MCQs and record which recovery check found the mismatch.
